Whole Disk Encryption causes "Process has not been completed" alert on every boot

I installed veracrypt 1.19 on 3 computers and started a whole disc encryption with aes. After successful encryption i get an message an every Windows (10 Home) boot :

You have scheduled the process of encryption or decryption of the system partition/drive. The process has not been completed yet.Do you want to start (resume) the process now?

If I press yes to continue I got another message:

There is no interrupted process of encryption/decryption of the system partition/drive to resume.\n\nNote: If you want to resume an interrupted process of encryption/decryption of a non-system partition/volume, select 'Volumes' > 'Resume Interrupted Decryption'.

But there are no unfinisehd encryptions. If if check the state of volume C:\ i got 100% encrypted.

I decrypted the disk and reboot the PC. I still got the message, even no drive is encrypted anymore.
I searched for the "systen encryption.xml" but i could not find it in any directory. I searched also by command line.

So I removed Veracrypt and the message disapeared. I installed veracrypt, disabled all anti Virus, disabled uac, so i do not need to permit special action, started veracrypt as Administrator. While Setting up the disc encryption the "System encryption.xml"
is shown the mentioned directory. After 100% encryption and rebooting the file is removed but the message pop ups on every login to Windows.
